of commercial shipboard satellite sys- tems, has introduced its TV-at-Sea sys- tems, which transmit satellite television programs to ships in all the major ocean areas. A fully stabilized anten- na is part of the Model 2494 system, which locks the satellite onto the ship as it pitches and rolls. An RCA DDS receiver is provided as part of the sys- tem, and decodes the digital program- ming from DIRECTV and USSB.

IGC Satellite Services provides cruise ship passengers with the tech- nology to make phone calls, send faxes and e-mail, access the Internet and make use of video conferencing while at sea. According to a compa- ny rep, "Our maritime experts are tak- ing the cruise industry into the twenty- first century by allowing passengers on a cruise to communicate how and when they want." One-minute calls cost a reported $9.50.

Ateliers & Chantiers du Havre To

Supply Cruise Ship Fin Stabilizer

Ateliers & Chantiers du Havre (ACH) will supply its Alpha-Fin stabilizer to

Chantiers de I'Atlantique for installa- tion on cruise ship Paul Gaugin build- ing at the French yard for Radisson

Seven Seas Cruises. The fin system, the result of 30 years of experience in roll stabilization for merchant and mil- itary vessels, consists of a main body with two associated trailing edge fixed flaps. According to ACH, the cavita- tion tunnel and towing tank tests have

July, 1996 illustrated several hydrodynamic advantages associated with use of the fin stabilizer, namely: 35 percent improvement in lift coefficient; 35 reduction in drag coefficient; a larger stall angle; and a reduction in cavita- tion in the common operating range.

These factors will combine to reduce drag motion, resulting in increased fuel savings. Risks associated with jamming flap joints are also avoided; as the new fin has been stripped of fin/flap joints — making it simpler to manufacture and easier to maintain.

GE Secures Disney Orders
